[0078] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0079] At present, with the development of display technology, various screens are used in different devices with their unique advantages. For example, the types of screens may include Liquid Crystal Display (LCD) screens and Organic Light-Emitting Diode (OLED) screens. LCD screens have a more natural display effect for image information, while OLED screens have a more vivid display effect for image information. Electronic devices mostly use LCD screens and OLED screens, and smart home devices mostly use LCD screens. Since electronic devices and smart home devices can be interconnected, smart home devices such as smart gateways, smart TVs, and smart refrigerators can receive and display image information such as photo information and video information transmitted by electronic devices. However, due to different screen types, the display colors of the same image information in different devices are different. Since different devices have different display colors for the same image information, the display effect of the image information is poor, which affects the user's viewing experience.

[0080] To address the above technical issues, the present disclosure provides a screen color adjustment method to reduce the difference in display colors between different screens. By determining the target color information of a target screen using the reference color coordinates of a reference screen, image information can be displayed with consistent colors on both the target screen and the reference screen, thereby improving the image information display quality.

[0081] The present disclosure provides a method for adjusting screen color. Figure 1 As shown, the method includes:

[0082] S100: Obtain reference color coordinates of a reference screen.

[0083] S200 : Adjust the color coordinates of the target screen according to the reference color coordinates to obtain target color coordinates.

[0084] S300 : Determine target color information of a target screen according to target color coordinates, where the target color information is used to determine a display color of the target screen.

[0085] In this embodiment, by determining the target color information using the reference color coordinates of the reference screen to adjust the display color of the target screen, the image information can be displayed in consistent colors on the target screen and the reference screen, thereby improving the image information display effect.

[0086] It is understandable that the image information can be displayed in consistent colors on the target screen and the reference screen means that the image information can be displayed in the same or similar colors on the target screen and the reference screen, but not necessarily in exactly the same colors.

[0087] Exemplarily, the reference screen is a screen different from the target screen. For example, when the reference screen is an LCD screen, the target screen can be an OLED screen. When the reference screen is an OLED screen, the target screen can be an LCD screen. It is understood that the reference screen and the target screen are not limited to LCD and OLED screens, but can also be plasma screens, cathode ray tube (CRT) screens, etc. The reference screen refers to the screen used as a reference during the color information adjustment process, and its color information does not need to be adjusted. The target screen refers to the screen whose color information requires adjustment. That is, the display color of the target screen is adjusted to be consistent with the display color of the reference screen.

[0088] For example, the target color information is information used to determine the display color of the target screen. The target screen can be displayed in a corresponding color based on the target color information. For example, the target color information can be information in a 3D display look-up table (LUT) or information in a color card.

[0089] In one embodiment, the reference color coordinates of the reference screen obtained in step S100 are determined as follows:

[0090] Gets the reference color coordinates of the reference screen when displaying different pure color images.

[0091] In this embodiment, since the image information is displayed in different color combinations, individual colors need to be adjusted when adjusting the display colors of the target screen. By displaying different pure color images on the reference screen and obtaining the corresponding reference color coordinates, the color coordinates of each color can be obtained for color adjustment, thereby improving the accuracy of the target screen display color adjustment.

[0092] It is understandable that the embodiment of the present disclosure does not limit the number of pure color images, and the number of pure color images can be, for example, 10, 20, 100, etc.

[0093] In one embodiment, if Figure 2As shown, in step S200, the color coordinates of the target screen are adjusted according to the reference color coordinates, and the target color coordinates are determined as follows:

[0094] S210 : Determine the reference color coordinates of the target screen in the first color space according to the reference color coordinates.

[0095] S220 , calibrate the reference color coordinates in the second color space to obtain target color coordinates.

[0096] In this embodiment, the reference color coordinates are used to determine the base color coordinates of the target screen in a first color space, thereby matching the color coordinates of the target screen and the reference screen. Because the target screen and the reference screen are different, even when the color coordinates match, there will still be differences in the display quality. The base color coordinates are calibrated in a second color space to reduce the difference in display quality between the target and reference screens, thereby obtaining the target color coordinates of the target screen. By calibrating the base color coordinates determined in the first color space in the second color space, the color consistency between the target and reference screens is enhanced, thereby improving the quality of image information display.

[0097] Exemplarily, the first color space and the second color space are different color spaces. The first color space and the second color space can be, for example, an XYZ color space, an RGB color space, a Lab color space, a YUV color space, a Yxy color space, or the like.

[0098] In one embodiment, Figure 3 As shown, in step S210, the base color coordinates of the target screen in the first color space are determined according to the reference color coordinates by:

[0099] S211, executing the display measurement step.

[0100] S212 . Compare the first color coordinates obtained by performing the display measurement step with the reference color coordinates in the same color space to obtain a first comparison result.

[0101] S213 : When the first comparison result meets a preset condition, determine a reference color coordinate according to the first color coordinate.

[0102] S214 : When the first comparison result does not meet the preset condition, adjust the reference color coordinates and continue to perform the display measurement step.

[0103] Among them, such as Figure 4 As shown, the step of executing the display measurement in step S211 is determined by the following method:

[0104] S215 : Convert the reference color coordinates into second color coordinates in the third color space.

[0105] S216: Control the target screen to display with the second color coordinates.

[0106] S217: Measure the first color coordinates of the target screen.

[0107] In this embodiment, when determining the reference color coordinates in a first color space, the reference color coordinates are converted into second color coordinates in a third color space, enabling the target screen to display using the second color coordinates. When the target screen displays using the second color coordinates, the first color coordinates of the target screen are measured to determine the difference between the first color coordinates displayed on the target screen and the reference color coordinates of the reference screen. Within the same color space, the first color coordinates are compared with the reference color coordinates to obtain a first comparison result, thereby determining the difference between the first color coordinates and the reference color coordinates. When the first comparison result meets a preset condition, the difference between the first color coordinates and the reference color coordinates is small, and the reference color coordinates are determined based on the first color coordinates. When the first comparison result does not meet the preset condition, the difference between the first color coordinates and the reference color coordinates is large, and the target screen fails to meet the reference color coordinate requirements. The reference color coordinates are adjusted, and the display measurement step is continued to ensure that the first color coordinates match the reference color coordinates. Through display, measurement, comparison, and adjustment, appropriate first color coordinates are selected to determine the reference color coordinates, thereby enhancing the color consistency between the target screen and the reference screen.

[0108] Exemplarily, the third color space is a color space different from the first color space and the second color space. The third color space may be, for example, an XYZ color space, an RGB color space, a Lab color space, a YUV color space, a Yxy color space, or the like.

[0109] Exemplarily, the comparison in step S212 between the first color coordinates obtained by the display measurement step and the reference color coordinates is performed in the same color space. If the first color coordinates and the reference color coordinates are not in the same color space, the first color coordinates can be converted to color coordinates in the color space containing the reference color coordinates before comparison, or the reference color coordinates can be converted to color coordinates in the color space containing the first color coordinates before comparison. If the first color coordinates and the reference color coordinates are in the same color space, the first color coordinates and the reference color coordinates can be directly compared, or the first color coordinates and the reference color coordinates can be converted to color coordinates in a color space other than the color space containing the first color coordinates and then compared. For example, if the first color coordinates are in the XYZ color space and the reference color coordinates are in the Yxy color space, the first color coordinates can be converted to the Yxy color space and then compared with the reference color coordinates. If the first color coordinates are in the XYZ color space and the reference color coordinates are in the Yxy color space, the reference color coordinates can be converted to the XYZ color space and then compared with the first color coordinates. If the first color coordinate and the reference color coordinate are both in the XYZ color space, the first color coordinate and the reference color coordinate may be converted into the Yxy color space and then compared.

[0110] Exemplarily, the comparison in step S212 between the first color coordinates obtained in the display measurement step and the reference color coordinates can be performed by subtracting the first color coordinates from the reference color coordinates in each dimension to obtain a coordinate difference, or by comparing the first color coordinates to the reference color coordinates in each dimension to obtain a coordinate ratio. For example, the first color coordinates and the reference color coordinates are color coordinates in a Yxy color space, where the first color coordinates are (Lv1, x1, y1) and the reference color coordinates are (Lv2, x2, y2). The difference between Lv1 and Lv2 is ΔLv, the difference between x1 and x2 is Δx, and the difference between y1 and y2 is Δy.

[0111] In one embodiment, the reference color coordinates are determined according to the first color coordinates in step S213 by:

[0112] When the first color coordinates are color coordinates in the first color space, the first color coordinates are determined as reference color coordinates.

[0113] When the first color coordinates are color coordinates outside the first color space, the first color coordinates are converted into color coordinates in the first color space as reference color coordinates.

[0114] In this embodiment, when calibrating color coordinates in the second color space, the calibrated color coordinates must be in the first color space. If the first color coordinates are within the first color space, they are directly determined as the reference color coordinates. If the first color coordinates are outside the first color space, they are converted into the first color space and used as the reference color coordinates. By predetermining the color space in which the first color coordinates reside and converting them when necessary, the reference color coordinates are set to the color coordinates in the first color space for calibration, thereby improving the reliability of color coordinate calibration.

[0115] Exemplarily, the adjustment of the reference color coordinates in step S214 may use the first color coordinates as the reference color coordinates, or may increase or decrease the reference color coordinates in each dimension. Alternatively, the reference color coordinates may be first converted to color coordinates in a color space other than the color space in which the reference color coordinates reside, then adjusted or decreased, and finally converted to color coordinates in the color space in which the reference color coordinates reside as the adjusted reference color coordinates. For example, the reference color coordinates are color coordinates in the XYZ color space. The reference color coordinates are first converted to color coordinates in the Yxy color space, and then the coordinates Lv1, x1, and y1 in each dimension are increased by ΔLv1, Δx1, and Δy1, respectively, and finally converted to color coordinates in the XYZ color space as the adjusted reference color coordinates. ΔLv1, Δx1, and Δy1 may be pre-set values, such as ΔLv1 being a positive value less than 5, Δx1 being a positive value less than 0.001, and Δy1 being a positive value less than 0.001. When the color space is converted based on the reference color coordinates, it can be implemented using a conversion matrix and an inverse conversion matrix of the color coordinates. The conversion matrix and the inverse conversion matrix correspond to the color space before and after the conversion of the reference color coordinates.

[0116] In one embodiment, Figure 5 As shown, the conversion of the reference color coordinates into the second color coordinates in the third color space in step S215 is determined as follows:

[0117] S2151. Obtain vertex color coordinates of the target screen in the third color space.

[0118] S2152. Determine a color coordinate conversion matrix based on the vertex color coordinates.

[0119] S2153 . Convert the reference color coordinates using a color coordinate conversion matrix to obtain second color coordinates.

[0120] In this embodiment, vertex color coordinates of the target screen in a third color space are acquired and their positions within the third color space are determined to obtain the color structure of the target screen in the third color space. A color coordinate conversion matrix is ​​determined based on the vertex color coordinates to convert the reference color coordinates into second color coordinates. By using the vertex color coordinates to determine the color coordinate conversion matrix and then converting the reference color coordinates, the accuracy of the reference color coordinates is increased, thereby improving the reliability of color coordinate matching.

[0121] Exemplarily, the third color space is an RGB color space, the reference color coordinates are color coordinates in the XYZ color space, the vertex color coordinates are the color coordinates of the four vertices R, G, B, and W, and the color coordinate conversion matrix is ​​a conversion matrix from the XYZ color space to the RGB color space. After multiplying the reference color coordinates by the color coordinate conversion matrix, they are converted to the second color coordinates in the RGB color space.

[0122] Exemplarily, in step S216 , the target screen is controlled to be displayed using the second color coordinates, a polynomial color correction (PCC) matrix may be generated according to the second color coordinates, and then displayed on the target screen using the PCC matrix.

[0123] In one embodiment, the first comparison result includes a coordinate difference between the first color coordinate and the reference color coordinate in each dimension. The preset condition includes that each coordinate difference is less than a preset limit of the dimension.

[0124] In this embodiment, the first comparison result includes the coordinate difference between the first color coordinates and the reference color coordinates in each dimension. The preset condition includes that each coordinate difference is less than a preset limit for that dimension, so that the first comparison result converges to the preset limit. Because the preset condition that each coordinate difference is less than the preset limit for that dimension is used, the first color coordinates match the reference color coordinates due to being identical or close, thereby improving the reliability of color coordinate matching.

[0125] Exemplarily, the first comparison result includes the coordinate difference values ​​△Lv1, △x1, △y1 of each dimension, and the preset limit values ​​of each dimension include 5, 0.001, 0.001. Then the preset conditions include △Lv1 less than 5, △x1 less than 0.001 and △y1 less than 0.001.

[0126] In one embodiment, Figure 6 As shown, in step S220, the reference color coordinates are calibrated in the second color space to obtain the target color coordinates determined by the following method:

[0127] S221 : Convert the reference color coordinates into third color coordinates in the second color space.

[0128] S222: Obtain display effect information of the reference screen and the target screen.

[0129] S223: Compare the display effect information of the reference screen and the target screen to obtain a second comparison result.

[0130] S224 . Calibrate the third color coordinates according to the second comparison result to obtain target color coordinates of the target screen in the fourth color space.

[0131] In this embodiment, when the reference color coordinates match the reference color coordinates, there is still a certain difference in the display colors of the target screen and the reference screen, and the reference color coordinates of the target screen need to be calibrated. The reference color coordinates are converted into third color coordinates in the second color space to facilitate adjustment of the color difference. Display effect information of the reference screen and the target screen is obtained and compared to obtain a second comparison result reflecting the difference in display effect information. Based on the second comparison result, the third color coordinates are calibrated to reduce the difference in color display between the reference screen and the target screen. The target color coordinates of the target screen in the fourth color space are obtained through calibration to determine the target color information of the target screen so that the display colors of the target screen are consistent with those of the reference screen, thereby improving the effect of image information display.

[0132] Exemplarily, the first color space is an XYZ color space, the second color space is a Lab color space, and the conversion of the reference color coordinates into the third color coordinates in the second color space in step S221 is determined as follows:

[0133]

[0134] Among them, L, a, b are the third color coordinates in the Lab color space, p 00 、p 01 、p 02 、p 10 、p 11 、p 12 、p 20 、p 21 and p 22 are the coefficients of the conversion matrix for converting from XYZ color space to Lab color space, and X, Y, and Z are the reference color coordinates in the XYZ color space.

[0135] Exemplarily, display effect information is used to reflect the color display effect, including brightness, color difference, and so on. Since, when the baseline color coordinates match the reference color coordinates, the display effect information observed by the user between the reference screen and the target screen still differs to a certain extent, to reduce the impact of the difference in display effect information on the user, the third color coordinate is calibrated. This calibration can utilize a pre-trained calibration neural network model. The calibration neural network model can be trained using a large amount of image information provided by the user and automatically calibrates the third color coordinate.

[0136] Exemplarily, the fourth color space is a color space different from the first color space, the second color space, and the third color space. The fourth color space may be, for example, an XYZ color space, an RGB color space, a Lab color space, a YUV color space, a Yxy color space, or the like.

[0137] For example, in step S224, the third color coordinates are calibrated based on the second comparison result to obtain the target color coordinates of the target screen in the fourth color space. After the calibration of the third color coordinates is completed, the third color coordinates are the color coordinates in the second color space. When obtaining the target color coordinates of the target screen in the fourth color space, the target color coordinates can be obtained using a conversion matrix that converts the second color space to the fourth color space, a conversion matrix that converts the second color space to the first color space, and a conversion matrix that converts the first color space to the fourth color space. Alternatively, the target color coordinates of the target screen in the fourth color space can be obtained by measuring the target color coordinates.

[0138] In one embodiment, if Figure 7 As shown, the target color information of the target screen is determined according to the target color coordinates in step S300 in the following manner:

[0139] S310: Obtain fourth color coordinates of the reference screen in a fourth color space.

[0140] S320 : Determine the compensation color coordinates according to the target color coordinates and the fourth color coordinates.

[0141] S330 : Determine target color information according to the target color coordinates and the compensation color coordinates.

[0142] In this embodiment, since the target color coordinates are determined based on the consistent display effects of the reference and target screens, the fourth color coordinates of the reference screen in a fourth color space are obtained to determine the difference between the target color coordinates and the fourth color coordinates in the fourth color space. Based on the target color coordinates and the fourth color coordinates, compensating color coordinates are determined as the difference, and target color information is then determined based on the target color coordinates and the compensating color coordinates. By determining the target color information based on the target color coordinates and the compensating color coordinates, the display color of the target screen is adjusted to ensure consistency between the display colors of the target screen and the reference screen, thereby improving the quality of image information display.

[0143] Exemplarily, obtaining the fourth color coordinates of the reference screen in the fourth color space in step S310 can be obtained by measuring the fourth color coordinates of the reference screen in the fourth color space, or by converting the reference color coordinates into a conversion matrix from the color space where the reference color coordinates are located to the fourth color space.

[0144] For example, in step S320, the compensation color coordinates are determined based on the target color coordinates and the fourth color coordinates. The difference between the target color coordinates and the fourth color coordinates in each dimension can be used as the compensation color coordinates. For example, if the fourth color space is a YUV color space, without considering brightness, the target color coordinates are (U1, V1) and the fourth color coordinates are (U0, V0). The difference between the target color coordinates and the fourth color coordinates in each dimension is ΔU = U1 - U0, ΔV = V1 - V0, and the compensation color coordinates are (ΔU, ΔV).

[0145] In one embodiment, Figure 8 As shown, in step S330, the target color information is determined according to the target color coordinates and the compensation color coordinates in the following manner:

[0146] S331. Obtain reference color information of a reference screen.

[0147] S332 : Determine, based on the reference color information, a fifth color coordinate in the fourth color space whose distance from the target color coordinate is within a preset threshold range.

[0148] S333 , compensating the fifth color coordinates with the compensation color coordinates to obtain sixth color coordinates.

[0149] S334: Determine target color information according to the sixth color coordinate.

[0150] In this embodiment, reference color information of a reference screen is obtained as a basis for determining target color information. Since the reference color information includes multiple color coordinates in a fourth color space, a fifth color coordinate whose distance from the target color coordinate in the fourth color space is within a preset threshold is determined. The fifth color coordinate and the target color coordinate are the corresponding color coordinates for the reference and target screens. If the target color information is determined directly based on the fifth color coordinate, the displayed colors of the target screen and the reference screen will differ. The fifth color coordinate is compensated with the compensating color coordinate to obtain a sixth color coordinate, and the target color information is determined based on the sixth color coordinate. By finding the fifth color coordinate corresponding to the target color coordinate and compensating for it, the color difference between the target screen and the reference screen is reduced, thereby improving the image information display quality.

[0151] Exemplarily, the reference color information is information used to determine the display color of the reference screen. Acquiring the reference color information of the reference screen in step S331 may be acquiring information of the reference screen in a 3D LUT.

[0152] For example, in step S332, based on the reference color information, fifth color coordinates whose distance from the target color coordinates in the fourth color space is within a preset threshold range can be determined. The reference color information can be converted entirely into color coordinates in the fourth color space, and then the color coordinates whose distance from the target color coordinates is within the preset threshold range are determined as the fifth color coordinates. That is, there can be multiple fifth color coordinates. For example, if the reference color information is information about the reference screen in a 3D LUT, each RGB node in the 3D LUT can be converted into color coordinates in the fourth color space under the P3 color gamut, and then the color coordinates whose distance from the target color coordinates is within a preset threshold range are determined as the fifth color coordinates. The preset threshold range can be determined based on the accuracy of the reference color information. The higher the accuracy of the reference color information, the smaller the preset threshold. The lower the accuracy of the reference color information, the larger the preset threshold. For example, the preset threshold can be 1.5 times, 2 times, 3 times, or other times the distance between two adjacent RGB nodes in the 3D LUT.

[0153] For example, in addition to determining the fifth color coordinates whose distance from the target color coordinates in the fourth color space is within a preset threshold range based on the reference color information in step S332, the fifth color coordinates whose distance from the target color coordinates in the fourth color space is the smallest can also be determined based on the reference color information. For example, if the fourth color space is a YUV color space, without considering brightness, the target color coordinates are (U1, V1), and the fifth color coordinates are (U2, V2), then Among them, s min Indicates the minimum distance between the color coordinates of the reference color information converted into the YUV color space and the target color coordinates.

[0154] For example, in step S333, the fifth color coordinates are compensated with the compensated color coordinates to obtain the sixth color coordinates. The sum of the fifth color coordinates and the compensated color coordinates in each dimension can be used as the sixth color coordinates. For example, if the fourth color space is a YUV color space, the fifth color coordinates are (U2, V2), and the compensated color coordinates are (ΔU, ΔV), then the sixth color coordinates are (U2+ΔU, V2+ΔV).

[0155] For example, in step S334, the target color information is determined based on the sixth color coordinates. The sixth color coordinates can be converted into RGB nodes in the 3D LUT as the target color information. Because the reference color coordinates are obtained when the reference screen displays different pure color images, there are multiple sixth color coordinates, which can constitute each RGB node in the 3D LUT.

[0156] In one embodiment, after determining the target color information of the target screen according to the target color coordinates in step S300, the screen color adjustment method further includes:

[0157] Write the target color information to the device where the target screen is located.

[0158] In this embodiment, by writing the target color information into the device where the target screen is located, the target screen can be displayed with adjusted colors to achieve consistency with the color display of the reference screen, thereby improving the effect of image information display.

[0159] For example, before the target color information is written into the target screen, the device where the target screen is located may have initial color information, and the target color information is used to adjust or overwrite the initial color information; the device where the target screen is located may also not contain the initial color information, and the target color information is directly written into the device where the target screen is located.

[0160] The present disclosure provides a preview screen display method, such as Figure 9 As shown, the method includes:

[0161] S400: Obtain reference color coordinates of a reference screen when displaying different pure color images.

[0162] S410: Execute the display measurement step.

[0163] S420 : Compare the first color coordinates obtained by performing the display measurement step with the reference color coordinates in the same color space to obtain a first comparison result.

[0164] S430 : When the first comparison result meets a preset condition, determine a reference color coordinate according to the first color coordinate.

[0165] S440: When the first comparison result does not meet the preset condition, adjust the reference color coordinates and return to step S410.

[0166] S450: Convert the reference color coordinates into third color coordinates in the second color space.

[0167] S460: Obtain display effect information of the reference screen and the target screen.

[0168] S470: Compare the display effect information of the reference screen and the target screen to obtain a second comparison result.

[0169] S480 : Calibrate the third color coordinates according to the second comparison result to obtain target color coordinates of the target screen in a fourth color space.

[0170] S490: Obtain fourth color coordinates of the reference screen in a fourth color space.

[0171] S500 : Determine compensation color coordinates according to the target color coordinates and the fourth color coordinates.

[0172] S510: Acquire reference color information of a reference screen.

[0173] S520 : Determine, based on the reference color information, a fifth color coordinate whose distance from the target color coordinate in the fourth color space is within a preset threshold range.

[0175] S540: Determine target color information according to the sixth color coordinate.

[0176] S550: Write the target color information into the device where the target screen is located.

[0177] In this embodiment, reference color coordinates are obtained for a reference screen when displaying different solid color images. A display measurement step is performed on a target screen, and the difference between the measured first color coordinates and the reference color coordinates is compared. When the first color coordinates match the reference color coordinates, reference color coordinates are determined based on the first color coordinates. When the first color coordinates do not match the reference color coordinates, the reference color coordinates are adjusted. The reference color coordinates are converted into third color coordinates in a second color space. Display effect information of the reference and target screens is obtained and compared to obtain a second comparison result. Based on the second comparison result, the third color coordinates are calibrated to ensure that the target and reference screens display consistent colors. Fourth color coordinates of the reference screen are obtained in a fourth color space. Compensating color coordinates are determined based on the target and fourth color coordinates. Fifth color coordinates whose distance from the target color coordinates is within a preset threshold are compensated using the compensating color coordinates. Target color information is determined based on the obtained sixth color coordinates, and the target color information is written to the device where the target screen is located. By determining the target color information based on the reference screen's reference color coordinates and adjusting the display color of the target screen, image information can be displayed with consistent colors on both the target and reference screens, thereby improving the image display quality.

[0178] Exemplarily, the first color space is an XYZ color space, the second color space is a Lab color space, the third color space is an RGB color space, and the fourth color space is a YUV color space. The reference color information is the information of the reference screen in a 3D LUT, and the target color information is the information of the target screen in a 3D LUT. Reference color coordinates in the XYZ color space are obtained when the reference screen displays different pure color images. Vertex color coordinates of the target screen are obtained in the RGB color space, and a color coordinate conversion matrix is ​​determined based on the vertex color coordinates. The reference color coordinates are multiplied by the color coordinate conversion matrix to convert them into second color coordinates in the RGB color space. The color coordinate conversion matrix is ​​a conversion matrix from the XYZ color space to the RGB color space. A PCC matrix is ​​generated based on the second color coordinates, and the PCC matrix is ​​used for display on the target screen. The first color coordinates of the target screen in the XYZ color space are measured. The first color coordinates and the reference color coordinates are converted into color coordinates in the Yxy color space and compared to obtain first comparison results ΔLv, Δx, and Δy. When the absolute value of ΔLv is less than 5, the absolute value of Δx is less than 0.001, and the absolute value of Δy is less than 0.001, the first color coordinate is determined as the reference color coordinate. Otherwise, the reference color coordinate is converted to color coordinates in the Yxy color space, adjusted, and converted to color coordinates in the XYZ color space as the adjusted reference color coordinates. The display measurement step is repeated until the reference color coordinates are determined. The reference color coordinates are converted to third color coordinates in the Lab color space. Display effect information of the reference screen and the target screen is obtained and compared to obtain a second comparison result. The third color coordinate is calibrated based on the second comparison result and converted to target color coordinates in the YUV color space. The fourth color coordinate of the reference screen is obtained in the YUV color space. The difference between the target color coordinate and the fourth color coordinate in each dimension is determined as the compensation color coordinate. The reference screen information in the 3D LUT is obtained. Each RGB node of the reference screen in the 3D LUT is converted to color coordinates in the YUV color space in the P3 color gamut, and the fifth color coordinate with the smallest distance from the target color coordinate is determined. The sum of the fifth color coordinate and the compensation color coordinate in each dimension is used as the sixth color coordinate, and the sixth color coordinate is converted into the RGB node in the 3DLUT as the target color information, and the target color information is written into the device where the target screen is located.
